GENERAL DlPOlUIATION

This section describes the structure of the basic User Manual and its supplements (see Figure 1-1), instructions for using the basic manual, and ~ general description of the system.

ACS 86'" COMPUTER SYS~ PUBLICATION ORGANIZATION

Altos Computer Systems has designed a publication structure that differs from most user manuals. The purpose of this structure is fourfold:

(1) To provide accurate system information to the user as quickly as possible.

(2) To permit updating of more dynamic areas of information as design improvements and system enhancements are achieved.

(3) To isolate and identify information blocks so that referencing time is minimized.

(4) To present information in a general-to-specific manner, thus meeting the needs of beginning users as well as more experienced users.

PRBLIIIIIlARY 8611 USER IIAlIUAL SBCrIOR 1. ~ODUC~IOR

The publications you receive with the computer are divided Into three groups (see Figure 1-1):

1. Column 1 of Figure 1-1 illustrates the forms that accompany the manual, and the Basic User Manual sections and appendices which contain rela ti vely unchanging information pertaining to all models in the series.

2. Column 2 illustrates Altos Supplements 3, 4, 5 and 6, which contain more dynamic information pertaining to executing diagnostic programs, installing operating systems, using Altos utilitiy programs, and installing upgrade and add kits. The supplements are designed to be inserted into the User Manual after the shipping container is unpacked.

3. Column 3 illustrates Supporting Manuals, which include pre-printed manuals produced by developers of related software products that operate on the ACS 8699 Computer System. This group may also include more informal technical notes related to such systems, thus insuring that you have the most current' information possible.

GENERAL SYSTEM DESCRIPTION

The Altos ACS 8699 Computer System is a multi-user system designed to fit many commercial, technical, industrial, scienti f ic, and educa tional applica tions, as well as many personal, home-computer applications.

This system is designed to perform larger, more complex tasks for more users than other microprocessors. Larger word size allows the use of more powerful instructions and direct addreSSing of more memory. The system requires fewer instructions and fewer computer cycles to accomplish the same job. It can handle complex' rna thema tical problems, larger da ta

PRBLIIIIJIARY 86.. OSER IIAIIOAL S~IOR 1. IlI'.mODUC'lIO!l

base searches and other demanding applications in far less time. More powerful processing capability, larger memory, and special memory man~gement techniques extend multi-user capabilities and allows multi-tasking without long waits for service.

Al though the ACS 8600 Computer System is particularly designed to meet mul ti-user and mul ti-tasking requirements, i t may also be configured as a powerful single-user system. The enhanced computing power of the system is achieved not only through the use of the Intel 8086 sixteen-bit microprocessor chip technology, but also through the use of a separate Intel 8089 Direct Memory Addressing (DMA) I/O processsor, and a unique hardware memory management scheme that greatly increases efficient use of main memory.

The Central Processing Unit (CPU) is the proven 8086 16-bit HMOS microprocessor. It operates at a fast 5 Mhz and can address I-Mbyte of memory. The CPU uses assembly language compa tible with the 8080 and 8085 processors, and performs 8- and 16-bit signed and unsigned arithmetic functions in binary or decimal, including multiplication and division operations.

The ACS 8600 family uses more than one processor. While the 8086 serves as the master CPU, other-processors are dedicated to special tasks. For example, a second processor, one 8089 DMA, handles direct memory accessing for I/O processing. The optional mathematical processor (8087 Floating Point Processor) handles mathematical functions. Although each processor is optimized for its own special task, they all wor k toge ther to shar e the workload for faster execution and decreased response time.

While many mid-sized minicomputer memories lack Error Correction Code (ECC), the ACS 8600 improves operational reliability with its own ECC. The memory has full error detection for single-bit and double-bit errors, and automatic correction of single-bit errors, thus reducing system errors and increasing the already-high system dependability.

The design of the ACS 8600 family of computers includes 500,000 bytes (500-Kbytes) of random access main memory. Main memory is expandable to one- million bytes (l-Mbyte) with full error detection and correction. It also includes I/O controllers for supporting a variety of peripherals such as an additional hard disk, CRT terminals, printers, magnetic tape units and floppy disk uni ts. Full communica tions suppor t, including asynchronous, bisynchronous and networking capabilities are also provided.

ACS 8600 proprietary memory management system assigns a logical-to-physical address translation and various attributes to each 4-Kbyte block of memory so that the non-contiguous physical memory can be assigned to any given task. This capability reduces the need for swapping users or tasks out to disk. The result is

PRELIMINARY 8611 USER IlAllUAL SECTION 1. IRTRODOCTION

that data base sorting, and other tasks requiring large memory are performed faster. The system also provides write and access protection to increase reliability and performance.

Altos Computer Systems supports and distributes four of the most popular operating systems, Control Program Monitor (CP/M-86), Multiple Program Monitor (MP/M-(CP/M-86), OASIS-16, and XENIX

(UNIX, Version 7). More than 300,000 current users of CP/M, MP/M and OASIS can easily upgrade their systems to the ACS 8600 Computer System knowing that their application software is compatible with the ACS 8600 computer.

BASIC, COBOL, PASCAL, and FORTRAN languages are also distributed and supported by Altos Computer Systems.

Although Altos does not generally distribute application program packages, i t does provide a l i s t of such compatible program packages, developed by leading software houses, on request.

Syste. Functional Description

The ACS8600 Computer System is an advanced-design, 16-bit, general-purpose computer manufactured by Altos Computer Systems. System design supports up to I-Mbyte of Random Access Memory (RAM) with full error detection and correction, and a wide variety of mass storage peripherals. Unique memory management hardware increases efficiency of main memory use. The system can be easily extended to meet the requirements of a wide variety of applications.

The ACS 8600 System is based on the Intel 8086 microprocessor family. While the system is primarily designed to meet multi-user and multi-tasking requirements it may easily be configured for large single-user applications. The following list summarizes the main features and capabilities:

Hardware Functional Description

The ACS 8688 Computer System is capable of supporting from one to eight users. The system is designed around a single printed circuit board which contains most of the processing resources. This single board computer also contains interfaces

PRELIIlIBARY 8611 OSER MAlIOAL SECTION 1. IRT.RODOCTION

permitting i t to be expanded to handle very large computing tasks. The system architecture is shown in Figure 1-5.

CENTRAL PROCESSING UNIT

The Central Processing Unit (CPU) of the system is based on three members of the Intel 8~86 microprocessor family. The primary processor, the 8~86 l6-bit HMOS microprocessor, is responsible for executing nearly all code. An 8~89 Dual Channel DMA I/O Processor is arranged with the 8~86 in a local configuration. The primary purpose of the 8~89 is to provide 16-bit-wide DMA I/O transfer capability. An optional 8~87 Numeric Data Processor (NDP) can perform high-speed floating- point calculations for the 8~86. The 8~87 NDP co-decodes instructions fetched by the 8~86 and will bus-request the 8~86 as required to perform the arithmetic operations.

SYSTEM MEMORY

System Memory is implemented with 64-Kbyte dynamic RAM devices and 2732-type Erasable-Programmable- Read-Only-Memory (EPROM) devices. The system permits up to l-Mbyte of RAM which maybe overlayed by the EPROM. RAM memory is organized as l6-bit words with six extra bits used to support error correction. RAM memory is divided into eight banks of twenty-two devices which provide l28-Kbytes of memory per bank~

Four lower banks of the memory (containing 5l2-Kbytes of RAM) are located on the CPU Board; four upper banks (containing an additional 5l2-Kbytes of RAM) are located on the optional expansion memory board. RAM memory is suppor ted by three other blocks of logic; the memory controller, the error correction circuitry and the memory manager.

MEMORY CONTROLLER

The memory controller allows word-organized memory to be accessed either as words or as bytes, assures proper memory refreshing, provides timing for the error correction circuitry, and notifies the CPU when memory data is ready. Nearly all of this logic is implemented in Large Scale Integrated (LSI) devices. An LSI dynamic RAM controller device and programmable logic arrays provide memory control.

RANDOM ACCESS MEMORY (RAM)

The RAM memory of the ACS 8600 is equipped with an LSI device that can detect all single-bit and double-bit errors when data is read from the RAM array. When a word is read back from the memory, check bits are also read and checked. If the check bits compare then no error has occurred but if the check bits do not compare then one or more data or check bits are in error. The error correction code is chosen so that the syndrome generated by the checking process can be used to indicate which single bit is in error.

If a data bit is in error it is corrected by inverting but, if a check bit is in error, i.t is simply reported. This method of error correction can only correct single-bit errors. However, single-bit errors are the most frequently occurring errors. When an error is detected the syndrome and the address associated with the error are latched and the CPU is interrupted.

When the CPU services the interrupt, it can perform a scrubbing operation to attempt to remove the error. The CPU can also log the error for diagnostic and maintenance purposes and indicate if the error was successfully scrubbed.

MEMORY MANAGEMENT

The purpose of memory management is to provide both pOSition independence and memory protection. The 8600 System uses an Int~l

8086 microprocessor as the computing and controlling element. This processor provides pOSition independence through the use of segment registers.

The 8086 generates addresses which allow it to access one million (1,048,576) bytes of memory, however this memory must be accessed in blocks of 64K (65,536) bytes. Limited protection is provided by the fact that the memory beyond the current four 64K segments cannot be accessed without altering the segment register. No limit checking or segment overlap protection is provided by the processor. Furthermore, any program may access the segment regi ster sat any time.

EXTENDED MEMORY MANAGEMENT

The 8600 system extends the memory management facilities of the 8086 by supporting write protection, access protection, limit

PRELIIIIlIARY 8688 USER IlARUAL S~IOR 1. III'mODOC'rIOR

checking and non-contiguous memory allocation. Finally the memory manager implements the concept of privileged instructions. The purpose of privileged instructions is to prevent application programs from al tering the system environment. By definition an application program must run with interrupts enabled and must make all I/O access requests through the operating system. Therefore hardware inhibits all I/O operations while applications programs are executing and the memory manager will generate an interrupt if it detects either the execution of a HALT instruction or the resetting of the interrupt-enable flip-flop while the system is running an application program.

PAGES IN MEMORY

The one million bytes of main memory are managed as 256 pages of 4K (4,~96) bytes each. Each page is assigned a relocation value, and thirteen flag and control bits. This memory relocation and attribute data is stored in a static RAM.

When memory is accessed, the relocation value is used to map the access onto the desired physical memory location. At the same time attribute bits are examined to test the validity of the access.

The violation port is the first of the three error reporting registers supported by the memory manager. This 16- bit register indica tes the type of memory access violation that has occur red. Two other I/O ports are used to report the address at which the violation occurred.

ERASABLE-PROGRAMMABLE-READ-ONLY-MEMORY (EPROM)

The system contains 8-Kbytes of Read Only Memory (ROM) pr i mar ily intended for bootstr apping purpose s. Thi s memory is currently implemented with two 2732 type Erasable Programmable Read Only Memory (EPROM) devices. However the hardware can be strapped to accommodate 27l6-type devices if less EPROM memory is required. This memory overlays the uppermost 8-Kbytes of the 1-Mbyte RAM memory space when 2732-type devices are used.

When 27l6-type devices are used the uppermost 4-Kbytes of RAM are overlayed. This memory can be switched out of memory to permit access to a full Mbyte of RAM. Boot memory contains a unique system serial number that permits software to be "locked" to a specific hardware system. In addition to the serial number, boot memory contains system configuration information.

FLOPPY DISK CONTROLLER

The main board of the ACS 860~ system contains a floppy diskette controller. This controller is implemented with LSI devices and can support up to four 8-inch floppy diskette drives operating in either single-density or double-density recording mode.

PRBLIIIDIARY 8611 OSER IlAlmAL sacrIOR 1. IRT.RODOC~IOR

HARD DISK CONTROLLER

The system provides additional high-speed mass storage through a generalized parallel interface to a family of rigid disk controller boards that mount directly to the CPU board. This interface can support rigid disk controllers with an a-bit data path. This type of rigid disk controller and interface provides a future growth path that permits the support of 5-inch Winchester disks as well as other disk drive technologies.

The initial member of the family of daughter boards provide a controller for the 8-inch Winchester-type hard disks. The controller supports one or two drives, giving mas~ storage capability ranging from lS- to as-Mbytes.

PARALLEL INTERFACE

A 24-bit programmable parallel interface is provided on the main system board. This interface is primarily for driving high-speed line printers but may be reconfigured (by software) to support a wide variety of applications •. It is implemented with an a255 Programmable Peripheral Interface (PPI) device which contains thr ee 8-bi t por ts. Por ts A and B of the a255 ar e buffered with bi-directional buffers that permi~ these ports to be used for either input or output. - Port C is buffered with a unidirectional buffer that provides three bits of input and five bits of output. The buffer ing on Port C supports the handshake and interrupt signals used by port B in mode one.

SERIAL CHANNELS

The system provides a m1n1mum of two, and a maximum of eight serial channels. Two channels are contained on the main CPU board and are primarily intended for standalone operation in manufacturing test. The other eight are contained on an Intelligent Serial Concentrator Board. One channel on the CPU board can be strapped fot either synchronous or asynchronous operation. This multipurpose channels can be strapped to interface to a variety of networks operating at data r~tes up to ass kilobits per second. All serial channels on the CPU board are supported with fully vector ed inter rupts.

(Some system configurations may be offered·which will not include the Intelligent Serial Concentrator Board.)

INTELLIGENT SERIAL CONCENTRATOR

;

The Intelligent Serial Concentrator Board consists of a zas processor with eight serial channels under its control. This board interfaces to the main board through the Multibus interface. The Z8S processor communicates with the aS86 via main memory and a pair of interrupt lines. The aSa6 may interrupt the zas and the zas may interrupt the aSa6. The eight serial channels are capable of operating in asynchronous mode at all

PRBLIIIIlIARY 8688 OSER DIIOAL SBC'rIOR 1. IJrmOOOC'fIOR

standard baud rates between 119 baud and 38.4 kilobaud.

In addition, one channel has provisions for external clocking on both transmit and receive clocks to support bi-synchronous serial devices. Each serial channel has a corresponding programmable timer for baud rate generation to allow for independent baud rates. This board is intended to decrease activity in the host processor so that the majority of character interrupt processing may be handled by the Intelligent I/O. This should allow the host processor to devote more of ita power to higher level tasks and handle users in a more timely fashion.

MAGNETIC TAPE UNIT DRIVE CONTROLLER

A magnetic tape drive controller, capable of controlling up to eight tape transports, can be mounted on the CPU board. This controller controls a DEI Funnel Tape Transport with a the codec' and controller options installed. This combination provides complete archival and backup capability for the rigid disks on the system.

MULTIBUS CARD CAGE

An additional enclosure, containing a standard Multibus card cage, can be connected through rear-panel connections on the primary enclorure. This expansion capability allows system users to add custom interfaces to the system. The interface supports both 8-bit and l6-bit bus masters that use the daisy chain technique ,for resolving the priority of bus requests. Multibus interface design includes socketed termination resistors for all Multibus signals that must be terminated on one of the bus masters. The signals in the int~rface meet the electrical and driver-receiver requirements of the Multibus Specification published by Intel.

CORVBlftIORS

Altos Computer Systems manufactures equipment for both domestic and foreign markets. Domestic equipment operates on lIS-volt AC power; foreign equipment operates on 239-volt AC power. Domestic equipment is identified by an RAR after the model designator on the back panel identfication plate; foreign equipment is identified by an RER. This convention is sometimes reflected in the part numbering scheme, wherein the final three digits "99lR usually designate domestic-use parts and n992 n usually designate foreign-use parts. For brevity, the final three digits of part numbers may be omitted in this manual.
